Question

If f(x) = -x + 5 and g(x) = x^2, what is (g° (-1)?

Answer 1

please refer to the above attachment.

36 is the right answer.

Answer 2

`(g\circ f)(-1)=36`

Explanation:

We are given the two functions:

`f(x)=-x+5\text{ and } g(x)=x^2`

And we want to find:

`(g\circ f)(-1)`

This is equivalent to:

`=g(f(-1))`

So, evaluating f(-1) first, we acquire:

`f(-1)=-(-1)+5=6`

Then by substitution:

`=g(6)`

So:

`=(6)^2=36`

Therefore:

`(g\circ f)(-1)=36`

Your answer is indeed correct.
